FAQs on Tests

Color vision tests that consist of different colored circular dots are all called pseudoisochromatic color vision tests. The Ishihara, Dvorine, and this online Waggoner PIPHRR color vision test are all pseudoisochromatic color vision tests. This test is not the Ishihara but it is a pseudoisochromatic color vision test. The Waggoner PIPHRR computerized test is considered Ishihara compatible.

Color vision test booklets, such as the Ishihara, only screen for color vision deficiencies — giving a "yes" or "no" result. The Waggoner PIPHRR gives a diagnosis: it tells you if you have a color vision deficiency, what type (deutan, protan, and/or tritan), and how severe it is (mild, moderate, or severe). Additional advantages include standardization of the test where each person is given the same time interval on each test plate, and no cues from a person administering the test.

The test has proven itself reliable and is in ongoing validation. Dr. Terrace L. Waggoner, developer of the Waggoner PIPHRR, has created several other validated color vision tests. The same proven confusion colors are used here. Research is currently being conducted by the Naval Aerospace Medical Institute (NAMI), the Federal Aviation Administration (FAA), Southern California College of Optometry (SCCO), Naval Medical Research Unit-Dayton Wright-Patterson AFB, and Southern College of Optometry, Memphis, TN.

A multitude of organizations currently use TestingColorVision.com, including the U.S. Navy, U.S. Army, Kaiser Permanente, and many hospitals, staffing agencies, and optometry offices worldwide.

The viewing time of the Waggoner Pediatric PIPHRR has been increased to give pediatric/geriatric subjects more time to respond compared to the Waggoner PIPHRR. The answer selection is on the same page as the test plate on the Waggoner Pediatric PIPHRR.

Absolutely. Our software development team would be more than happy to work with you developing a color vision testing module that works with your learning management system.

Naval Aerospace Medical Institute is currently comparing it to a 14 PIP test, Farnsworth Lantern, Richmond HRR, and a Nagel Anomaloscope. Preliminary findings have found it more reliable than the PIP, Farnsworth Lantern, and Richmond HRR. The Waggoner PIPHRR is 100% in agreement as far as the type of color vision deficiency with the Nagel Anomaloscope — the gold standard for evaluating color vision tests.

Pseudo-Isochromatic Plate Hardy Rand Ritter. Hardy, Rand, and Ritter were three doctors who developed the American Optical HRR.

There are numerous industries that either require or recommend normal color vision, including aviation, military, law enforcement, electrical work, medicine, and many others. A full list of these industries and occupations can be found on our Testing Uses & Benefits page.
